Lengkungan alami, jembatan alami atau kadang disebut lengkungan batu adalah susunan batu alami dengan lengkungan yang terdapat sebuah lubang di bawahnya. Lengkungan alami umumnya terdapat pada tebing daratan, tebing pantai, sirip, atau tumpukan yang disebabkan oleh erosi air laut, sungai, atau proses pelapukan oleh cuaca.[1][2][3][4][5][6]
